CAMERA.

1'0 all whom, it may concern:

Be it known that. I, WILLIAM J AX LITTLE, of Newton, in the county ofMiddlesex and State of Massachusetts, a citizen of the 5 United States,have invented a new and useful Improvement in Qarneras, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specifi- IO cation,in explaining its nature.

My invention relates to a camera or that kind of a device in which theimage of an exterior objectis projected on a plane surface. The especialobject of my invention is to provide a camera in which there may be useda plate coated with some etching surface or ground like that referred toin my United States Patent No. 780,207, dated January 17, 1905, theplate being so arranged as to form one side or portion of the camera andon the under side of. which plate the image of an exterior object may beprpjected, whereby it may be traced upon the plate by cuts or incisionsmade in the etching ground or surface thereof.

My invention can best be seen and understood by reference to thedrawings, in'which Figure 1 shows the camera in perspective.

Fi 2 shows a vertical cross-section thereof, so taken at about themiddle of the camera.

Fig. 3 shows in side elevation the camera folded. Fig. 4 shows thecamera in plan, open, with sides folded in.

In the drawings, A re resents the camera,

3 5 preferably having the orm of a triangularox, as shown in Fig. 1. Itis also-preferably made of a folding or knockdown structure in orderthat when folded it may occupy as little space 'as possible or assume a,form 40 substantially as shown in Fig. 3, when it 'can be easily carriedin ones pocket. The camera accordingly is made up or corn rises thefollowing parts: The bottom or 5 coated on the outside with some etchingsurface or ground and which is translucent in order that an imageprojected upon the under side of said plate may be seen by lookingthrough the same, as will hereinafter. be explained. It may also benoted that I this etching-plate may consist only of a flexi-Specification of Letters Patent. Application filed February 21, 1906.Serial No. 302.175.

ble film having an etching surface or ground, 1 in which case there isprovided a backing for said film or plate consisting of an auxiliaryglass plate a, inserted in the frame back of the film. The etching plateor. film, together with its backing, is slippedinto the frame from thetop and is held in the frame by any suitable s'upportingefianges a Theface-plate a and plate-carrying frame a are adapted to fold down overthe side plates (1 a and meet at the apex thereof when the side platesare turned up to assume a vertical position with respect to the bottomplate a, all of which parts thus combined form a closed triangular box.The parts are held together thus in combination in the following manner:There are formed on the in" side of the face-plate a? and frame a justin from the edges thereof, flanges a, against which the side plates a care adapted to hear, when they are turned up toassume anUPI'ightfPOSllZ-lOIl, asaforesaid, forming the plates {are kept frombeing. turned outwardly beyond, a vertical upright position by flan es,a turnedup' alongfthje side edges of the baseor bottom plate There isalso a plate a near the 'topedgef thereof, against which the top ed'geof the frame is adapted to bear when the". arts al'illjl conjunction.The

While the camera is es ecially adapted to receive aplate like that a overeferred to, it

Having thus fully described my invention, 1 claim and desire to secureby Letters Patent of the United States- 1. A camera of the characterspecified comprising a closed, knockdown box of triangular form, thesame having a bottom or base plate, triangularly-shaped sides, aiaceplate hinged to one end of said bottom or base plate, and a framehinged to the other end thereof, Which frame is adapted to receive aplate or film, and which face-plate meet at the apex thereof, means forretainmg said sldes, face-plate and frame thus in conjunction, abulls-eye disposed in said faceplate, and a reflecting-surface insidethe camera on the bottom or base plate, and Which parts are so disposedthat the image of an exterior object passing through said bulls-eye Willall upon said reflecting-surface, bereflected thereby and projected uponthe under surface of said plate or film.

2. A camera of the character specified comprising a closed, knockdownbox of triangular i'orm, the same having a bottom or base plate,triangularly-shaped side plates hinged thereto, a face-plate hinged toone end of said bottom or base plate, and a frame hinged to the otherend thereof, which faceplate and frame are adapted to fold over saidtriangular sides and meet at the apex thereof, means for retaining saidsides, face-plate and frame thus in conjunction, a bulls-eye disposed insaid face-plate, a reflecting-surface inside the camera on the bottom orbase plate and a plate or film having a translucent and frame fold oversaid triangular sides and l l r l l 1 l l l etching surface or groundarranged inside said frame, which parts are so disposed that the imageof" an exterior object passing through said bulls-eye will fall uponsaid refleeting-surface, be reflected thereby and projected upon theunder side of said etching plate or film.
